modules.local now possible


If you happen to be testing kernel modules, DragonFly can now load them from a modules.local directory.  This keeps modules that aren’t part of the base system, separate.  This is probably of most use to developers.  Set local_modules=”YES” in rc.conf to enable.

bsdtalk264 – Down the Gopher Hole


BSDTalk 264 is out, and rather than an interview, it talks about a topic I’ve always enjoyed: Gopher, including ways to access Gopher resources even now.

NFS tuning tips


If you’re on DragonFly, or maybe even if you aren’t, and you are using NFS, here’s some tips on how to wring the best performance out of it.

BSDNow 139: Cheri-picking BSD


This week’s BSDNow has some news catchup, since they’ve been on the road, and an interview with Brooks Davis of FreeBSD-on-Cheri.  (CheriBSD?)

Old DragonFly users, please test


Not older people that use DragonFly, but people of any age using an older release of DragonFly: Bezitopo is Pierre Abbat’s topographical program, and he needs testers on versions 4.4 of DragonFly or before.  Please give his open-source program a run if you are on the appropriate versions.  Trying other BSDs, even though not requested, can’t hurt.

ACPICA update for qemu users


If you’re using qemu and DragonFly, the latest update of ACPICA to version 20160422 may fix some issues introduced in a previous update.  (I don’t have a specific bug report to point you at; sorry!)

DragonFly 4.4.3 released


The DragonFly 4.4.3 point release is out.  There’s a commit page listing the changes between 4.4.2 and 4.4.3.  Nobody will be surprised that there’s an OpenSSL update in there.

If you want a complete image, it’s available for download at your nearest mirror.  If you want to upgrade an existing install:

cd /usr; make src-update 
    (or  src-create-shallow if you don't already have source)
make buildworld && make buildkernel
make installkernel && make installworld
make upgrade
reboot

FreeBSD Mastery: Advanced ZFS out


I’d save this for an In Other BSDs note, but that’s a whole week away: FreeBSD Mastery: Advanced ZFS is published, available in electronic and printed editions.  I suspect this would be interesting to non-BSD users, too.

More Hammer fixups


Tomohiro Kusumi has been creating a near-constant stream of bugfixes and cleanups to Hammer for quite some time. I don’t often link to it, because they are incremental improvements and hard to linkblog, so to speak. In an effort to make up for this deficit, I do want to draw attention to his two recent commits: “Make hammer commands print root volume path“, and “Print volume list after volume-add|del“.  Small changes, but this is what makes complex systems usable.

Baytrail fix for DragonFly and others


If you remember this Baytrail problem, Daniel Bilik has gone and found a fix, as this appears to be a cross-platform bug, and he has patches for DragonFly.  If it’s affecting you, you don’t have to wait for the patches to be added in; he’s made them available directly.

Update: it’s committed to DragonFly now.

Many, many network connections


I keep posting about Sepherosa Ziehau’s work on sustaining extremely high traffic loads in DragonFly.  Now I’m posting about a tool to create that load: kq_sendrecv.  It creates tens of thousands of TCP connections, without creating a process for each, and uses kqueue, as you might guess from the name.  This may be useful if you really want to tax another system.

BSDNow 135: Speciality MWL


This week’s BSDNow has an interview with Michael W. Lucas, BSD author.  He often speaks at events, so it should be an enjoyable talk.

Book sponsorships ending soon


Normally I would save this for a “In Other BSDs” weekend edition, but it would be too late: if you want to get in on a book sponsorship for Michael W. Lucas’s next FreeBSD Mastery book, you have only a few days left to join in.  His last book sponsorship worked out perfectly, timing-wise.

garbage[19]: sched_yield


This week’s garbage[] podcast is up, to go with the BSDTalk interview, and they’ve made it to 20 episodes.    There’s a section at the end about cross-pollination (my favorite BSD term) which I have not been able to listen to yet, but I’m curious.

It’s zero-indexed, if that made you confused for a second.

Update: I listened, and the cross-pollination conversation matches my impressions too.  Decentralized leadership is a cause, I think.

unzip has been added to DragonFly, making it present in every BSD but I think OpenBSD.

UEFI for you and I


Imre Vadasz has added the ability to create a UEFI bootloader in DragonFly.  Can you use it?  I don’t know; I haven’t tried it yet and I can’t tell from the commit.

clang in DragonFly, soon


John Marino has added the starting framework to use clang as the alternate base compiler in DragonFly.  Note that it’s not hooked into the build yet.  This is the first non-GCC compiler added into DragonFly, so there’s some work yet before you can have an all-clang system.  This should replace GCC 4.7, which is the current alternate compiler.  GCC 5.0 is the default, if you didn’t know.

Note that clang is present in dports, so it’s already been available for general use, for some time.  This framework is for building DragonFly itself.

Multiple card slots accessible in DragonFly


If you somehow have a device with multiple SD/MMC card slots, you can now access all of them under DragonFly.  (Apparently done to make a tablet run DragonFly better, going by IRC conversation)

World rebuild needed for DragonFly 4.5


If you are running bleeding-edge DragonFly, Sepherosa Ziehau has made some networking changes that both reduce CPU usage in high-traffic situations and change some underlying network structures.  This means a full buildworld is needed on your next update.

If you’re using DragonFly 4.4.x or older, you are unaffected.

disklabel64 tips


If you find yourself using gpt and disklabel64 for a new disk, and aren’t quite sure what order to type everything in to create a disk slice, why not crib from Tim Darby’s notes?  (note that the archive has added some line breaks to it.)

BSDNow 132 and also AsiaBSDCon


BSDNow 132 is up, titled “Scaling up with BSD“, with an interview of host Allan Jude about ScaleEngine, plus a bunch of news links.  There isn’t the usual longer writing because they are currently at AsiaBSDCon, and I saw that there are streaming links for the events there.  Look at the schedule, watch, and I hope there’s saved video too.

Hammer not show


The ‘hammer show’ command can be used to dump the B-Tree structure of a Hammer volume, and CRC errors can be spotted.  It’s rare that anyone would need it, but if you do, this dumped information will include file hierarchy information.

If that makes you a bit nervous to repost any of that information when talking about it in public, Tomohiro Kusumi has added an ‘obfuscate’ option to ‘hammer show’ that does just that – it hides path information from the debug output.

Improvements for kqueue and per-CPU caching


Sepherosa Ziehau has continued his quest of making large-scale data transmission on DragonFly effortless; his latest change has cut the kqueue contention rate by two-thirds when dealing with a connection rate of nearly 400,000 connections per second.  Note that’s number of connections, without even tracking the bandwidth used by each.

New CPUTYPE variables


John Marino rearranged how GCC5 handles CPUTYPE settings.  If you are specifically setting the target CPU when compiling, his commit will give you an exact list of what to target.

Note that I am not saying another architecture – this is all x86_64.  I also don’t recommend doing this unless you have a specific use for it – compiler overoptimizations often create more problems than they fix.

i915, Baytrail, and C-states


Daniel Bilik has found there’s an issue with i915 acceleration, Baytrail CPUs, and some AUTODEEP low-power states.   This will only affect you if you are using that specific hardware combo and setting certain low power modes.  Interestingly, it affects other platforms, too, as it appears to be a symptom of how the video is addressed, not a DragonFly-specific bug.

Default shells and library changes


I see this bite people irregularly over the years: if your default shell on login can’t run, what do you do?  I’ve seen it happen because of a missing /usr/lib, and it can happen with out-of-date library references, too.   There’s several different ways to deal with it:

That last one may be useful if your dports setup gets mangled, somehow – though ‘pkg upgrade’ has always worked for me.

DragonFly i915 support: another upgrade


Francois Tigeot has again updated Intel i915 video support in DragonFly, bringing it even with what’s in Linux 4.2.  This will be very useful for Broadwell and Skylake users, and even Broxton, apparently the newest Atom platform.

Who still wants a shirt?


I have DragonFly shirts, helpfully printed up by Sepherosa Ziehau in China.  I have a list of people that are interested in shirts, most of whom remembered to give a shirt size.  I don’t have anyone’s email address or mailing address on that list.

If you are on that list, send me your mailing address.

The shirts are marked L/XL/XXL/XXXL, but they run smaller than U.S. versions of those sizes.  I usually find a U.S. XL shirt baggy, but “XXXL” is the one that fit me, for instance.  I’ll do my best to place the appropriate one.  This is just an advance apology, since it’s too late to change anything if it turns out tight.

I’ll mail these out as I have the spare cash and time on hand.  (I hope most of you live in the continental U.S.)
